It is +25
Negative fourth root of a number= 1/the fourth root of the number. Fourth root of 625= 5 (5*5*5*5) 1/5
2
Two to the fourth power times 5 to the fourth power equals 10,000
'Squared' & 'Square Root; are the inverse mathemtical functions. 5 (squared) = 25 square root of '25' is 5 Mathematically this would be written as Square ; 5 x 5 = 5^(2) = 25 Square Root ; sqrt(25) = 25^(1/2) = 25^(0.5) = 5 NB THis can be exteneded to 'cubes' and 'cube roots' e.g. 3 x 3 x 3 = 3^(3) = 27 curt(27) = 27^(1/3) = 27^(0.3333.....) - 3 And fourth power and fourth root. e.g. Fourth power ; 2 x 2 x 2 x 2 = 2^(4) = 16 Fourth root = (4th)rt(16) = 16^(1/4) = 16^(0.25) = 2 It can be exteneded to the 'nth power' and the 'nth root'. Where 'n' is any number.
If ( y ) is the principal square root of 5, then ( y ) must be a non-negative number such that ( y^2 = 5 ). This means ( y = \sqrt{5} ) and is approximately equal to 2.236. Additionally, since ( y ) is defined as the principal square root, it cannot be negative.
You multiply each of the numbers together and then take the nth principal root, where n is the number of values multiplied together. So Geometric Mean (2, 3, 4, 5) = fourth root of (2*3*4*5) = 120 = 3.31 (approx).
6251/4 = 5
A number will have both a positive and negative square root 5 x 5 = 25 and -5 x -5 = 25.
It is: 2/5
5.00
its 5 to the 4th power times 5 to the fourth power and the answer is 390625
Restricting the discussion to real numbers for now. In this case, the square root is only defined for non-negative numbers; the principal square root of a positive number is the POSITIVE square root. For example, both +5 and -5 are square roots of 25, since both - when squared - give you 25. But the positive square root (+5) is called the principal square root, and if you write the square root symbol, that's the number usually meant.
